This is an ESP32-Cheap-Yellow-Display-based weather clock that integrates indoor and outdoor environment monitoring and weather reminders. It’s perfect for home or office use.
📌 Left Screen:
- Current time and date (synchronized with NTP servers for accuracy)
- Indoor temperature and humidity (real-time detection via DHT22 sensor)
📌 Right Screen:
- City location (approximate location based on IP)
- Outdoor weather conditions (sunny, cloudy, rainy, snowy, etc.)
- Outdoor temperature and humidity (real-time data from Open-Meteo API)
📌 Bottom Smart Suggestions:
- Provides clothing and travel reminders based on the weather and time of day
- Example: "☔ Rain expected, take umbrella"
- Indoor temperature & humidity: DHT22 sensor (connected to IO22)
- Outdoor weather: Open-Meteo API for real-time weather updates
- Time synchronization: NTP servers to ensure clock accuracy
- Time-based reminders (morning / noon / evening / night)
- Weather-aware alerts (sunny, cloudy, foggy, rainy, snowy, thunderstorms)
- Extreme temperature warnings:
- Above 35°C → Heatwave alert
- Below 5°C → Cold weather warning
- Auto WiFi reconnect to prevent network issues
- Scheduled updates:
- Time: Periodically refreshed
- Weather: Fetched at set intervals
- Sensor data: Updated only when values change to save resources
- WiFi connection monitoring: If disconnected, the screen displays a “WIFI Disconnected”
This project is built with PlatformIO, supporting multiple hardware configurations. You can select different environments (env) for compilation based on their screen type:
- cyd (only have a microusb port): For ILI9341 screens
- cyd2usb (have an usb-c port and a microusb port): For ST7789 screens with RGB inversion and BGR color order adjustments
Additionally, the platformio.ini configuration file includes WiFi credentials, weather API keys, time zone settings, brightness, and update intervals, which you can customize based on their needs.
